Sorting Multiple Nodes

[Splurd]

my xml is sorted like this,

<staffdirectory>	<staffnames>		<staffname>			<id>123</id>			<name>bob</name>		</staffname>		<staffname>			<id>456</id>			<name>joe</name>		</staffname>	</staffnames>	<staffcategories>		<staffcategorie>			<code>1</code>			<name>Management</name>		</staffcategorie>		<staffcategorie>			<code>2</code>			<name>Engineer</name>		</staffcategorie>	</staffcategories>	<staffs>		<staff>			<id>123</id>			<code>1</code>		</staff>		<staff>			<id>456</id>			<code>2</code>		</staff>	</staffs></staffdirectory>
